The first matching circuit 42 is used for matching the output impedance of the antenna when the antenna radiator 10 is at the first position, that is, when the antenna is in the built-in state, so as to match the working frequency band of the antenna. The second matching circuit 43 is used for matching the output impedance of the antenna when the antenna radiator 10 is located at another position, that is, when the antenna is in an external state, so as to match the operating frequency band of the antenna. Since the distance between the antenna radiator 10 and the rf transceiver 30 increases when the antenna radiator 10 moves upward, an offset frequency is generated in the set operating frequency band.

Wherein the first matching circuit 42 and the second matching circuit 43 are at least one of a resistance matching circuit, a capacitance matching circuit, or an inductance matching circuit.
The low-frequency resonance of the antenna is lower due to the fact that the smaller resistance or the smaller inductance is increased, the low-frequency resonance of the antenna is higher due to the fact that the capacitance is increased, and the designated resonance is adjusted due to the fact that the combination of the inductance and the capacitance is increased.
In this application embodiment, when the antenna turned into external state by built-in state, be equivalent to the antenna and be in the external environment of pure sky, improved the radiation environment of antenna, promoted the radiation performance of antenna, nevertheless when being in same operating frequency range to built-in and external, because the change of radiation environment, can produce the off-frequency problem under the same operating frequency range. Therefore, in the embodiment of the present application, the first matching circuit 42 and the second matching circuit 43 are arranged to match different working environments of the antenna, so as to generate an effect of resonance optimization and improve the radiation performance of the antenna.
It should be noted that, in the embodiment of the present application, the second matching circuit 43 may further include several matching subcircuits 402 for matching different tuning parameters of the antenna.
Illustratively, the second matching circuit 43 comprises three matching subcircuits 402. As shown in fig. 5, each matching subcircuit 402 includes a series device or a parallel device, wherein the series device or the parallel device can be a capacitor or an inductor, for achieving impedance matching of the antenna radiator 10. The order of the parallel devices and the series devices is not limited; different matching sub-circuits 402 have different impedance values. Depending on the location, different matching sub-circuits 402 may be selected for access.
In a specific setting, the second matching circuit 43 includes a control switch 401 for switching the matching sub-circuit 402. The type of the control switch 401 is set according to the number of the matching subcircuits 402, for example, the second matching circuit 43 includes three matching subcircuits 402, the corresponding control switch 401 can select a single-pole-three-throw switch, and when more are included, a MUX (multi-way switch) or the like can be selected.
It should be noted that, in the embodiment of the present application, the electronic device includes a plurality of antennas, and frequency bands of different antennas are different. Therefore, for different telescopic antennas, different matching circuits and matching sub-circuits 402 may have different impedance values to adapt to matching tuning of antennas in different frequency bands.
In the embodiment of the present application, the electronic apparatus includes a main Board 80, such as a Printed Circuit Board (PCB).
